TCP places data in TIOA and corresponding entry into TCT.
KCP acquires the transaction identifier from TIOA and
verifies if it is present in PCT.
SCP acquires Storage in Task Control Area (TCA), in which
KCP prepares control data for the task.
KCP then loads the application programs mentioned in PCT by
looking for it in PPT.
If resident ? real storage memory location is not present in
the PPT the control is passed to PCP that loads the
application programs from the physical storage location
address given in PPT. The control is then passed to the
application program (LOAD module).

Answer / shobhit verma
STEP1 FIRST ENTER 1 TO 4 CHAR TRANSACTION ID
STEP2 THEN TCP COME INTO EXISTENCE AND IT WILL CHECK THE
TERMINAL IS THERE ANY REQUEST
STEP3 TCP INSTRUCT THE SCP TO ALLOCATE TIOA
STEP4 PASSES THE CONTROL TO KCP
STEP5 THEN KCP VALIDATES THE TRANSACTION ID
STEP5 REQUEST SCP TO CREATE TASK CONTROL AREA
STEP6 THEN TCP TRANSFER THE CONTROL TO PCP
STEP7 LOCATE THE PROGRAM AND LOADS IT
STEP8 AND TRANSFER THE CONTROL TO AP
STEP9 RETRIEVE THE FCP FOR FILES OPERATION
STEP10 SEND REQUEST TO SCP TO CREATE FILE CONTROL AREA
STEP11 THEN FCP INFORM THE KCP FOR TASK
STEP12 DISPATCHES THE NEXT TASK IN THE QUEUE
STEP13 TRANSFER THE CONTROL TO FCP
STEP14 FCP RETURN CONTROLS TO AP
STEP15 AP PROCESS THE DATA
STEP16 AND TRANSFER THE CONTROL TO PCP
STEP17 PCP TRANSFER CONTROL TO KCP TO END OF TASK
STEP18 KCP REQUEST TO SCP FOR DEALLOCATION OF MEMORY
STEP19 THEN TCP SEND THE OUTPUT TO TERMINAL
STEP20 REQUEST THE SCP TO RELEASE TIOA
